International postal money orders may be sent by Priority Mail Express International service, Priority Mail International service, First-Class Mail International service, or First-Class Package International Service.

When Form MP1 is used to send funds the purchaser should complete the information requested on both the money order and the customer’s receipt. Follow the instructions for preparing domestic money orders in DMM 503.14 when using Form MP1.The Postal Service is not liable for money orders that are lost before the purchaser completes this information. Money orders may be made payable to the purchaser (either a person or a firm) or a payee by official title (e.g., Director of Publications Canada).

Postal Service employees must not disclose information concerning money order transactions to any person except the purchaser, the payee, the endorsee, or a duly authorized agent of one of these. The Office of Accounting Postal Service Headquarters may authorize other requests only when the request concerns a specific money order or a specific party to a money order transaction and when accompanied by a valid court order.
